The number of active Covid-19 cases in Delhi has halved in just 12 days after rising to a high of 94,160 on January 13, while it took 21 days for the active caseload to drop by half during the second wave last year. The third wave of the pandemic saw the active cases peaking to 94,160 on January 13. The number dropped to 42,010 by Tuesday. 

During the ferocious second wave last year, active cases had risen to a high of 99,752 on April 28 and the number reduced to 45,047 by May 19. Experts said the decline in cases is in line with their expectations.

“It was expected. The rise was very rapid. The R naught value -- which indicates the spread of COVID-19 -- was around 4, which means a person would infect the entire family within two days.

“The recovery is faster. The incubation period is shorter, hardly two to three days. Hence, the sharp fall in the number of cases,” said Director-Professor, Community Medicine Department, Maulana Azad Medical College, Nandini Sharma.

Researches suggest that Omicron has an incubation period of roughly three days as compared to the Delta variant which had an average incubation period of about four days. 

The original strain of COVID-19 and its early variants had an incubation period of about five days. The Delhi Government data showed there have been fewer hospitalisations due to COVID-19 this time and officials said the virus isn't the primary reason for most fatalities. A maximum of 2,784 (17.96 per cent) of the 15,505 COVID-19 beds in hospitals were occupied on January 17. During the second wave,

20,117 (92 per cent) of the 21,839 beds were occupied on May 6. However, the increase in the number of patients on ventilators has been a cause for concern.
